KNOPPIX 5.3.1 Error:

Accessing KNOPPIX DVE at /dev/sr0 ... INS mod/ '/cdrom/KNOPPIX/modules/cloop.ko' : Input/Output Error
Can't find KNOPPIX file system, sorry
I've burned two cd's and two dvd's, lowest possible speed ... both have several files that won't open ... says files may be corrupt.

Can't open /cloop.ko ... says its corrupt

The correct cd is being read, but the files are corrupt.

Tried to mb5summary thing, but it doesn't list the iso files, so can't check 'em.

Jzip won't open several files, including /cloop.ko ... jZip says they are corrupt.

Traced it back to the downloads ... any idea where to download a good copy?
